Index Finger Fatigue Lab Report

Introduction: In Musculoskeletal system, during large amounts of physical activity the muscle will encounter fatigue, as a result of depletion of muscle glycogen or because of interruption of blood flow during contractions of the muscle as well the lack of oxygenation it provides to the muscles. To test this theory we will compare the time it take for the index finger and the muscles around it to reach fatigue after a variation of excises. We will compare these results in Mann (2014) to see how our results vary.

Methods: As per lab Manual, Wright, W. and Nankervis, S. (2016) Over a course of a minute, we will test the index finger fatigue levels by the intensity of the amount of resistance it had to carry, in this case an elastic band in sets of; one, two, four and eight. Combined with the amount of movement it has to complete as the bands doubled. For instances; 1 bend of the finger per second, over the course of one elastic band, followed by two elastic band and so on. It is to be noted, we also allow for rest between the ends of on tests to other to allow for the index finger to recover from the fatigue to get a more accurate response or sense of fatigue from the participant. The participant would state weather their where experiencing muscles
The error mark in red in table1 and graph 1, is an inconclusive results as the participants hand cramped up effecting the results. If we compare this too Mann(2014) figure 14-16 and 14-17, we can see a depression of fatigue as resistance and activity is increased. Mann(2014) states that; “Skeletal muscles produce the maximum force when they contract from the resting length.” Meaning that the first moments of activity the muscles is and resting length and as we excises the short that length is meaning the maximum forces less with
